INITIATION OF INSTANT REPLAY

Managers may initiate replay review on one reviewable play per game by verbally indicating his intention to challenge, in a timely manner, to the crew chief. Guidelines will be established to determine whether a challenge is timely.

The manager may request that the umpire review multiple portions of the same play, but he must specify exactly which portions of the play he is challenging.

If any portion of a challenged play is overturned, the manager who challenged the play will retain the ability to challenge one more play during the game. No manager may challenge more than two plays in a game.

Once the manager has exhausted his ability to challenge plays during the game and after the beginning of the seventh inning, the crew chief may choose to invoke instant replay on any reviewable call. In that circumstance, the crew chief is not obligated to invoke instant replay if requested by the manager. If a manager has a challenge left, he can still use it after the seventh inning, if necessary.

Home run calls that are currently subject to instant replay review will continue to be reviewed at the crew chief's discretion. Managers may request that an umpire review a home run call, but managers cannot challenge home run calls.
